Product Description

PSC-300-S KIT Midtronics DC Power Supply / Battery Charger 30 Amps

PSC-300-S Midtronics Power Supply Battery Charger Fully Automatic, Regulated DC output 30 Amps, internal breaker and on/off switch and case

Midtronics PSC Power Supply Chargers provide clean, reliable power for charging and maintaining battery state-of-charge. These chargers/maintainers are designed for use during service reflashing, complex maintenance, or on the showroom floor where vehicle demonstrations can make significant demands the battery. In power supply mode, the PSC converts 120 volt AC line input into a virtually noise-free, nominal 13.4 volt DC output. In battery charger mode, the PSC delivers current up to the rated value for charging any voltage-depressed 12 volt lead-acid battery. Once fully charged, the PSC detects battery condition and tapers current output to to sustain accessory loads or offset any parasitic drain.

Product Features

  • Advanced switch-mode design
  • Provides a cleaner, more reliable power source than using a standard charge
  • Fully-regulated DC output prevents overcharging of the battery and provides precise control to maintain the necessary battery voltage during complex service and reflash
  • Multiple protection features for a long, trouble-free life:
  • Reverse battery polarity protection via replaceable fuses
  • Brownout input protection
  • Over-current protection; cycle-by-cycle peak limiting and rated current-limiting to maximize the life of the converter
  • Over-temperature protection
  • Quiet, small, and compact for portability
  • Commercial design and heavy-duty internal components ensure years of continuous use
  • Unique proportional fan control circuit
  • Sets the fan speed directly proportional to the converters internal ambient temperature
  • Enables the fan to turn on and off very slowly, minimizing unwanted fan-starting noise
  • High quality, detachable cables for easy field service
  • Optional protective carrying case for storage or during use
